We May Be An Inexperienced Couple But...
The story of Ikuma and Sumika, two childhood friends who recently got married and started a brand new life together. At first sight, they seem like a happy couple with nothing to worry about, there is one problem: they have trouble having sex together. With both of them having zero prior experience, this awkward couple tries their best(?) to figure out how to do it for the first time.
